SPRING-SCALES.

SPECIFICATION forming part of Letters Patent No. 444,093, dated January 6, 1891.

Application filed September 9, 1890- Serial No. 364,440. (No model.)

in Spring-l'lalanees, of which the following is a specification.

My invention relates to that form of springbalance commonly known as a straight spring-balance; and it consists in certain de tails of construction and in combination of parts, that willbe more fully hereinafterspecitied, reference being had to the accompanying drawings, forming a part hereof, wherein Figure l isa front view of thebalance, showing the plate bearing the graduated scale. Fig. 2 is a face view of the same without the face-plate. Fig. 3 is a rear view of the same, and Fig. -.'l a cross-section of theback plate 011 the line a c of Fig. 2.

It has heretofore been customary in scales of this nature to form the back plate in two pieces riveted together in suitable manner,

and to attach a loop at the upper end, and attach the spring to any suitable in'ojection on the inside of the back plate. liy my invention the entire back plate is stamped in one piece, and then being perforated to receive the bail, the spring is attached to the inner portion of the bail.

In the drawings, the letter A represents the face-plate of the balance bearing the graduated scale.

1- represents the back plate formed with a longitudinal bulge and side flanges, as in Fig. 4.

D is the spring usual in spring-balances of this nature.

F is an arm suspended from the spring and carryin the usual pointer E, and also a hook H, which is adapted to carry the article to be weighed. The said spring D is attached by a hook or loop (I to the inner cross-bar g of the bail G. The ball G passes through suitable perforations h h in the back plate. At the lower end of the back plate B, in the edge thereof, a small slit 1) is cut to permit the arm ii to slide freely in and out between the two plates A and B. It will be seen that no part of the weight on ll is borne by the parts A and 13.

Having described my invention, what I claim is In a spring-balance, the back plate B, having the bulge stamped integral therewith, combined with the bail G, said bail penetrating into the bulge and having an inner cross-bar g connected to and combined with the spring D, and the weight-carrying arm F, substantially as described.
